INSTALLATION INSTRUCTIONS

1. Set parking brake on vehicle and disconnect the negative battery terminal.

2. Loosen the two hose clamps and remove inlet air tube connecting the throttle body and airbox. Disconnect PCV, I.A.C. (Idle Air Control) tube, and inlet air temperature sensor connector, if applicable.

3. Disconnect the return spring from the linkage and unhook the throttle cable by opening the throttle by hand and slipping the cable from the cam groove. Disconnect the cruise control cable, if applicable.

4. Disconnect the T.P.S. (throttle position sensor) connector.

5. Remove the four bolts securing the throttle body to the intake and remove the factory throttle body.
NOTE: For Optimum Performance, match the intake opening to the new throttle body size. Although this is not mandatory, it will maximize intake flow.

6. Using the supplied screws and gasket install the new throttle body on the intake manifold and secure.

7. Re-attach the throttle cable, T.P.S. sensor connector, return spring and cruise control cable, if applicable.

8. Re-install inlet tube between airbox and throttle body. Be sure to reconnect the PCV tube, idle air control tube and inlet air temperature sensor if applicable.

9. Re-connect the negative battery cable.

10. Start the engine and run until it is at operating temperature.
NOTE: If you are unable to obtain a steady idle and proper idle speed, continue with steps A and B below:

A. Shut off engine, and be sure the idle valve adjustment screw (gold colored, slotted head) is turned clockwise until it bottoms in its bore. CAUTION: Do not use too much force when bottoming the screw.

B. Start the engine and disconnect I.A.C. connector. Adjust gold idle screw in small increments until vehicle idles at approximately 500 rpm. Re-connect I.A.C. connector and vehicle will return to computer controlled idle speed.

11. Shut off Engine and double check all fasteners and clamps to ensure they are all secure.
